IronScheme 1.0 Beta 2 Released

There are three Microsoft developed languages that use the Dynamic Language Runtime: IronRuby, IronPython and a closed source language that only runs on Silverlight - Managed JScript.

IronScheme is a 'community-developed' language that also runs on .NET through the DLR. IronScheme includes a Visual Studio plugin (for VS 2008 SP1) and IronScheme 1.0 Beta 2 has just been released.

IronScheme aims to be a R6RS conforming Scheme implementation.

• 1.0 Beta 2 Release Notes

New in the 1.0 Beta 2 release:

• Added a new LINQ library (ironscheme linq2) which implements all methods found under System.Linq.Enumerable. The new version also uses deferred execution
• Added a few more libraries
• Added (ironscheme unsafe) library
• Many bug fixes
• Added P/Invoke functionality, and a small FFI layer
• Many compiler optimizations added (TCE, lambda body hoisting, assignment elimination), more coming for beta 3!
• Rewrote fixnums and flonums in Scheme. Uses unsafe features.
• Memory optimizations (previous versions had many objects that could not be GC'd), much less GC's needed now

A codeproject article takes you through installing and playing with the new release - including calling .NET libraries from Scheme.

Personally I'd like to play around with calling into Python from Scheme and vice-versa...
